NAUSEA, VOMITING, AND NUTRITION IN PREGNANCY

描述：仅在美国就有超过5万名女性 每年因怀孕期间恶心和呕吐而住院。 此外，研究研究和美国生命统计数据证实 每年约有400万孕妇将经历 怀孕期间出现某种形式的恶心和呕吐。虽然早(少) 怀孕期间的恶心和呕吐可能与 积极的结果，晚期(超过20周)恶心和 妊娠期呕吐(NVP)不太确定，一直以来 与出生体重下降和婴儿脱水有关 母亲。然而，恶心和呕吐的营养影响 怀孕期间的呕吐几乎是未知的。一些研究表明 表明改变饮食摄入量可能会减轻这种影响。 怀孕期间有恶心和呕吐的症状。该提案的目标是 是测量恶心和呕吐对营养的影响 人口状况对产前结局的影响 怀孕的女人。 这项研究以奥雷姆的自我照顾缺陷理论为概念，将 对孕妇进行描述性相关研究 要：(1)确定恶心的频率、严重程度和持续时间 和孕期呕吐；(2)确定与 恶心和呕吐的人口学变量和营养摄入量 特征；以及(3)确定其营养关系 未出现恶心症状的妇女在怀孕期间的恶心和呕吐 以及怀孕期间的呕吐。生活质量将被衡量 与怀孕期间的恶心和呕吐建立关系的时间。 人体测量，食物频率，饮食摄入量，产妇 并将进一步检查分娩结局和自我护理机构 以确定它们与早期和晚期恶心呕吐的关系 在怀孕期间。

DESCRIPTION: More than 50,000 women in the United States alone are hospitalized for nausea and vomiting in pregnancy each year. Furthermore, research studies and the U.S. Vital Statistics confirm approximately four million pregnant women per year will experience some form of nausea and vomiting in pregnancy. While early (less than 20 weeks) nausea and vomiting in pregnancy may be associated with positive outcomes, the outcomes of late (over 20 weeks) nausea and vomiting in pregnancy (NVP) are less certain and have been associated with decreased birth weights and dehydration of the mother. However, the nutritional implications of nausea and vomiting in pregnancy are virtually unknown. Some studies have suggested that alterations in dietary intake may allay the effects of nausea and vomiting during pregnancy. The goal of the proposal is to measure the effects of nausea and vomiting on nutritional status with implications for prenatal outcomes in populations of pregnant women. This study, conceptualized with Orem's Theory of Self Care Deficit, will be a descriptive correlational study of pregnant women implemented to: (1) determine the frequency, severity, and duration of nausea and vomiting in pregnancy; (2) determine the relationship of demographic variables and nutrient intakes to nausea and vomiting characteristics; and (3) determine the nutritional relationships of nausea and vomiting in pregnancy to women not experiencing nausea and vomiting in pregnancy. Quality of life will be measured over time for relationships to the nausea and vomiting in pregnancy. Anthropometric measurements, food frequencies, dietary intakes, maternal and birth outcomes and self care agency will be further examined to determine their relationships with early and late nausea and vomiting in pregnancy.
